Commonsense reasoning has been seen as one of the key ability for intelligent machines to perform various activities [1]}. SemEval 2020 Task 4 [2]} is a commonsense validation and explanation task which is inspired by Wang et al. DBLP:journals/corr/abs-1906-00363. This task consists of three subtasks. The first subtask is to choose the one which makes sense from two natural language statements with similar wordings; The second subtask is to decide among three options the most crucial reason why a given statement does not make sense; The third subtask requires the machine to generate the reasons.
